We discuss the relevance of the lattice Boltzmann method (LBM) for soft matter alongside other simulation methods. We set up a popular problem of self-assembly of Janus spheres by combining native fluid and particle models in LBM with a simple amphiphilic pair potential. Thermal fluctuations and close contact corrections are also incorporated along with a novel periodic boundary condition for finite-sized 3D particles. Preliminary results of Janus sphere self-assembly are presented and compared with similar works in the literature. We also comment on the difficulties that LBM faces tackling such problems.

使用格子玻尔兹曼方法自组装两亲性Janus球

我们与其他模拟方法一起讨论了格子Boltzmann方法（LBM）与软物质的相关性。我们通过将LBM中的自然流体和颗粒模型与简单的两亲对势相结合，建立了Janus球自组装的普遍问题。热波动和紧密接触校正也与有限尺寸3D粒子的新型周期性边界条件结合在一起。提出了Janus球自组装的初步结果，并将其与文献中的类似作品进行了比较。我们还评论了LBM面临解决此类问题的困难。
